This experimental study explores the role of the subgrade condition in influencing the power imparted to an above ground target by a surface explosion. By means of geotechnical centrifuge modeling, a variable level of ground stiffness was simulated by increasing the g-level in the soil. In addition to a soil base, a steel plate was also used to support the charge. To create the explosion, bridgewire detonators comprised of a mixture of PETN and RDX were used as primary charges. Quantitative sensor data on the power of the explosions was obtained using the newly developed Blast Impulse Response Gauge (BIRG). To capture the high-speed and powerful event more fully, other electrical instrumentation and a high-speed video camera were also deployed. To explore an alternative way to simulate blast effects, tests were also conducted using the compact dual-chamber shock canister that was developed and fabricated by the research group. By means of shadowgraph techniques, the shockwave phenomenon in an air blast was also captured. Response data obtained from both explosive and shock-canister blast simulations are compared and discussed.
